Jaw reflexes were recorded before and after neurosurgery of the trigeminal sensory root or the gasserian ganglion in 11 patients with idiopathic trigeminal neuralgia and in 2 patients with orbital malignancies. The reflex was also studied in three patients with unilateral midbrain lesions verified by postmortem findings. Jaw reflex abnormalities appeared in all cases, although there were no clinical or EMG signs of masseter dysfunction. Proprioceptive afferent fibers of the jaw reflex therefore seem to be mediated by the sensory and not the motor root. The afferent limb of the jaw reflex seems to run centrally through the midbrain, probably through the mesencephalic nucleus of the trigeminal nerve.
对11例原发性三叉神经痛患者和2例眼眶恶性肿瘤患者在三叉神经感觉根或半月神经节神经外科手术前后记录了下颌反射。对3例经尸检证实有单侧中脑病变的患者也进行了该反射研究。尽管没有咬肌功能障碍的临床或肌电图体征，但所有病例均出现下颌反射异常。因此，下颌反射的本体感觉传入纤维似乎由感觉根而非运动根介导。下颌反射的传入支似乎从中脑中央穿过，可能是通过三叉神经的中脑核。
